Description

The innovation relates to a device for automatically unloading rack trolleys and reloading them after the mechanical cutting process.

In the process of producing baked goods, such as cakes, pies or the like, a cutting process into individual items ready for sale is common in many cases. In companies with industrial production and high throughputs, cutting machines or automatic machines with ultrasound excited sonotrodes designed as cutting tools are mainly used, as these are particularly convincing in terms of their effectiveness and cutting quality.

In addition to a few isolated solutions with automatic assembly line technology, cakes and confectionery products are mainly provided for the cutting process on baking trays that are inserted in a rack trolley.

For this purpose, the sheets are usually removed manually by a worker from the carriage positioned in front of the cutting machine and placed on the feed belt of the cutting machine.

After the fully automatic cutting process has started, the sheet is conveyed out of the cutting area, removed and manually reinserted into the rack trolley. The workers who operate the cutting machine are largely occupied with handling the trays and the rack trolley.

Only the short period of time during the cutting process until the next sheet is placed or for repeated start is available for further work.

The state of the art in the bakery industry is predominantly characterized by the fact that, although highly effective cutting technology is available, approaches for a link with the upstream and downstream production steps for continuous production using intelligent, digitally networked systems are hardly available or known.

For these reasons, the aim of the innovation is an automatically working ultrasonic cutting system with a secure docking of the rack trolley to a removal device for the sheets and their return to the trolley after the cutting process.

In addition to linking all the necessary work steps, the option of being able to use the digitally available data for further upstream and downstream work steps should also be included.

The aim of the automatically operating system is also a significant saving in working time, since a local commitment of the operator is only required to bring the rack trolley, to start and to transport the trolley with cut goods.

This means that the time saved can be used for other necessary work tasks until the entire contents of the car have been completely processed.

The innovation is therefore based on the task of developing an ultrasonic cutting system in which, after a rack trolley is manually brought up, its entire contents in the form of baking trays with goods to be cut are automatically processed and then returned to the trolley.

For this purpose, after the trolley has been securely docked, a removal device should move to the respective positions of a sheet, remove the sheet, cut it according to the program and return it to the rack trolley.

At the same time, a digital sheet metal or goods identifier in connection with the control of the cutting machine should ensure the automatic selection of the cutting parameters in accordance with the recipe-related specifications and the existing data should also be available for further work steps.

According to the innovation, the object is achieved in that a known ultrasonic cutting system is modified in such a way that it represents the dominant core of the system and all other functional assemblies are assigned to the cutting machine and linked to its control.

The rack trolley ( 1 ) is manually attached to the unloading and loading device ( 2 ) introduced. In the trolley mounting module ( 6th ) of the unloading and loading device, a sensor detects the trolley and after the safe manual or automatic locking, the start of the system can be initiated with the further automatically running work steps and the sheets ( 3 ) can be removed with the baked goods to be cut.

The sheets used in the manufacturing process are provided with an RFID or bar code to which an entered product identifier for the goods to be cut is assigned.

The sheet metal code and product identification are used for the cutting process to automatically select the cutting parameters in accordance with the respective recipe-related program specifications from the cutting machine control ( 5 ) accepted.

The unloading and loading device ( 2 ) a removal device that can be moved vertically to any position ( 7th ).

The removal device also includes a horizontally movable holder ( 8th ), which is inserted below the sheet to be removed after moving to the respective sheet metal position.

The recording ( 8th ) has a swivel mechanism ( 9 ), which removes the sheet metal from the support rails of the rack trolley ( 1 ) takes off.

Then the raised sheet is pulled out of the carriage and the removal device ( 7th ) transfers after vertical approach to the cutting plane ( 10 ) the sheet metal on the feeder ( 11 ) to the ultrasonic cutting machine.

It is transported to the cutting machine, locked in the cutting area and the baked goods can be cut there with the appropriate specific parameters according to the product identification transferred to the control.

After the cutting process, the machine releases the sheet metal for further transport.

It becomes a transfer module ( 12th ), which works in the same way as the extraction device.

The sheet is taken over by the transfer module, lowered and below the cutting level by means of a return transport system ( 13th ) for reloading the rack trolley. Reloading takes place in reverse order to unloading.

The product data belonging to the respective sheets can be saved and used for subsequent work steps, such as order picking.

Of course, the innovation can also be used for cutting tasks using a simple cutting system modified for linking the individual modules without an ultrasonic cutting tool.

Further advantageous refinements of the innovation emerge from the claims, the descriptions of the mode of operation and in the drawing 1 illustrated embodiment.
